To all whom it 'may concern:

Be it known that I, JOHN M. FLITCRAFT, e citizen of the United States, residing et Elkhart, in the county ot Polk and State ot' lows, have invented certain new and useful i improvements in flicetylenc-Ges Generatore, otwhich the following is o specification.

My invention relates to improvements in acetylene gas generators, the primary object of the invention being to provide e generally improved generator of this class of simple, cheep, and ellioient structurebetter adapted to its intended purposes then eny other de-' vice of the same cless with which l ein acquainted. Y

The subsidiary objects of the invention may be stated as follows: first: to provide e generator adopted tosupply `es larger or smaller number of lights or burners and to ,automatically regulate the generation olf gos according to the number sind cepecity of lights or burners in use :it any time. To this end l employ en autornziticolly' reciprocating gas-holder which is filled ond depleted so es to maintain e substantially unitoriu pressure and constant supply oil gas ley eutoinaticolly regulating the generation of ges according to `the amount consumed. See ond: to provide o. ges generator which moy lie refilled or replenished with calcium cerloid Without in any Way disturbing or de-` pleting the supply of ges contained in the mein gesbell. y To this end. l employ en oureiliery ges-bell'c'erried Within seid mein gesbell end-provided with u rernoveble corliid receptacle. Third: to provide e. generator eclepted to supply c substantially constont pressure ot ges While'heinp; refilled. or re charged with eelciuin carbid. To this end ll. employ tivo gnsoineters connected to e. cornfinon service 'pipe ond adapted to lie connected to or disconnected from erich other and with or from the connnon service pipe according to the gesolneter being replenished et e given time.

With theV above mentioned ends in View, the invention in its present embodiment, consists .in the novel construction, strenge inent and combination. ot perte, liercinetter described, illustrated in the eccoinpeuying drawings,end perticulerly pointed out in the` appended cleini.

in Figs. 1, and 2, of the drawings. The lid or cover 17, is provided with a cross-bai` forming a loop handle 21, and oppositelydisposed projeotin lugs 22, and the said lid or cover is adapted to be secured by having said projecting lugs engage with and take under oppositely-disposed hooks 23, in a y,well known manner and as shown most clearly in Fig.' 2, of the drawings. l

The gas is generated in a well known manner by the contact of the carbid contained in the carbid chamber with the Huid contained in the tank 1, and when so generated is adapted to'pass into the main gasbell 5, through the medium of the gas-conduit pipes 24:, leading from the auxiliary gas-bell 9, into the top portion of the main gas-bell 5. Thegas conduit ipes 24, are provided with valves 25, exten ing through the top of the main gas-bell, and when it is desired to remove the carbid-receptacle or holder to replenish the same with fresh calcium carbid communication between the main and auxiliary gas-bells 5, an'd 9', may .be cut olf by means of the valves 25, after which the lid or cover 17, may be removed I and the carbid-receptacle lifted out of the auxiliary 'gas bell. If desired he carbidreceptaclemay be hung upon the hook 26, of the cross-bar 4, by means of the crossbar 27 (see Fig. 3), at the top of said carbid-receptacle. l

The mam gas-bells 5,v are adapted' to communicate with each other and with the service pipe 28, by means of horizontal outlet pipes 29, having vertical pipe portions 29, terminating in the upper portions of the fluid containing tanks and above the eXtreme upper level of the iluid contained therein. The outlet pipes 29, are.l provided with valves 30, by means 'of which communication between the gas -bells 5, and service pipe 28, may be turned on or olf as the exi encies of service and replenishing with ca cium carbid may demand.

As a means for providing for the escape of an over supply of gas when the main gasbells have been driven upwardly t their eX- treme capacity an escape pipe 31, is provided communicating at its lower end with branch pipes 32, said branch pipes 32, being provided with upwardly-extending vertlcally arranged pipe portions 32, `normally closed by means of depending bellipe valves 33, carried by the main gas-heli; 5. l

sans# The depending pipe valves 33, take or telescope over the upwardly-extending pipe portions 32, and as shown most clearly 1n Fig. 1, ot the drawings, are'normally submerged in the fluid contained in the main gas-bells 5. By this arrangement it is obvious that when the main gas-bells 5, have been driven upwardly to such a point th the lower ends of the pipe-valves 33, are carried out of the fluid, that the gas will be permitted to escape through the pipe valves 33, and out through the branch pipes 32, and escape pipe 31.

The valve cocks 34, at the T-portions of the service and escape pipes 28, and 3]., permit of the withdrawal of any water which may accumulate therein. The faucets 35, secured to the fluid containing tanks 1, enable the fluid to be withdrawn when desired.

From the foregoing description, taken in connection with the accompanying drawings, the advantages and operation of my invention will be readily understood.

Having thus described an embodiment of my invention, what I claim and desire to secure by Letters Patent vis,-

An acetylene gas generator, comprising companion generators each consisting of a tank, a main gas-bell, an auxiliary gas-bell carried by said main gas-bell in the upper portion thereof and provided with an annular external wa'er sealing recess, said auxiliary gas-bell having its ower edges terminating above the median portion of said main gas-bell, a removable carbid-receptaclel mounted in said auxiliary gas-bell and comprising inner and outer oraminous walls providing an intermediate carbid-chamber and a central o ening, a lid or cover having its rim normal y resting in said water-sealing recess, valved as-conduits normally connecting said auXi iary gas-bell'with said main gas-bell, a common service-pipe communicating with the main gas-bell of each of said companion generators, a common lescape-pipe connected to `the tank of said generators and provided with vertical ortions terminating within the main gasells and above the auxiliary gas-bells and carbid-receptacles, and depending bell-pipevalves carried by said main gas-bells and taking over and normally closing the vertical portions of said escape pipe by being submerged in the fluid in said tanks below 'said auxiliary gas-bells.

In testimony whereof I have afiixed my signature, in presence of two witnesses.
